Description
Technical field
The utility model relates to electrical component, particularly is used to protect the fuse of electrical equipment overload.
Background technology
The structure of fuse of the prior art is (seeing Fig. 1 and Fig. 2), the binding post energized, and the fuse-link end cap contacts with one of them conductive contact film.Because of this conductive contact film is a semicircular in shape, contact-making surface is little.When connecting through resistance R, electroluminescence body W, another one conductive contact film and fuse-link, because of they are shared cavity volumes, for conductive contact film is contacted with the fuse-link end cap, just must extend and this conductive contact film that extends, conductive contact film is long brought sizable resistance for the loading and unloading fuse (dress that can have, what have pulls out to come out, and the contact that has is bad).Two conductive contact film contacts area of cause are different, fuse-link can turn forward and cause fuse-link end cap and this two conductive contact film contacts area inhomogeneous, thereby in the process of energising, cause temperature to raise and burn contact-making surface, cause unnecessary outage, sometimes because of loose contact even initiation fire, and conductive contact film just is embedded in the fusing carrier shell, does not make it fixing, so also very dangerous.
Summary of the invention
The utility model provides a kind of V-arrangement spring-piece type fuse, change two conductive contact films into v-shaped structure, not only can shorten the length of conductive contact film, but also can keep the contact area unanimity of two conductive contact films, safe and reliable, as solve loose contact in the prior art, contact area to be inhomogeneous and mounting or dismounting are inconvenient technical problem.
The utility model realizes that the scheme of foregoing invention purpose is: design a kind of V-arrangement spring-piece type fuse, comprise the wiring base and be embedded in the interior year molten assembly of this wiring base, described wiring base is provided with two binding posts that can connect external cabling, molten assembly comprised a year molten assembly housing in described year, the deck of fuse member is installed, two conductive contact films that connect the fuse member two end electrodes, wherein first conductive contact film is electrically connected first binding post, and second conductive contact film is electrically connected second binding post; Described two conductive contact films all are converted into V-arrangement, and the tip of this V-arrangement conductive contact film probes in the deck, and at least one end of this V-arrangement conductive contact film is fixed on carries on the molten assembly.
Described fuse member is a cylindrical shape cap fuse-link.Molten assembly also was provided with spacing stop in described year, and this spacing stop one end is fixed in and carries on the molten assembly housing, and the other end extends to an end of deck, and described first conductive contact film and second conductive contact film are measure-alike.
Molten assembly was provided with resistance R and electroluminescence body W in described year, and this resistance R and electroluminescence body W series connection back connect two conductive contact films respectively by lead, and described electroluminescence body W partly is exposed to and carries molten assembly housing surface.One end of described two conductive contact films is fixed in by binding post respectively and carries on the molten assembly, and the two ends of the lead of described connection resistance R and electroluminescence body W connect above-mentioned two binding posts respectively.
After the utility model adopts above-mentioned technical scheme, make this novel fuse have contact well, be difficult for the characteristics of outage, and safe and reliable, and mounting or dismounting are convenient.

Embodiment
In conjunction with above-mentioned description of drawings specific embodiment of the utility model.
By among Fig. 3 and Fig. 4 as can be known, this V-arrangement spring-piece type fuse, comprise wiring base 10 and be embedded in the molten assembly 20 that carries in this wiring base 10, described wiring base 10 is provided with two binding posts 11 and 12 that can connect external cabling, molten assembly 20 comprised a year molten assembly housing 21 in described year, the deck 22 of fuse member 30 is installed, two conductive contact films 23 and 24 that connect fuse member 30 two end electrodes, wherein first conductive contact film 23 is electrically connected first binding post, 11, the second conductive contact films 24 and is electrically connected second binding post 12; Described two conductive contact films 23 and 24 all are converted into V-arrangement, this V-arrangement conductive contact film 23 and 24 tip probe in the deck 22, this V-arrangement conductive contact film 23 and at least one end of 24 are fixed on carries on the molten assembly 20, and described first conductive contact film 23 and second conductive contact film 24 are measure-alike.After fuse member 30 embeds deck 22, V-arrangement conductive contact film 23 and 24 tip just in time are against on two electrodes of fuse member 30, because first conductive contact film 23 and second conductive contact film 24 are v-shaped structure, behind its pressurized, can remain compressing to electrode, make both reach the purpose of good contact, and, this v-shaped structure is smooth contact for electrode, during mounting or dismounting, resistance ratios is less, and it probes into the conductive contact film that deck 22 interior length are far smaller than prior art, so, in the process of mounting or dismounting fuse member 30, the frictional resistance of first conductive contact film 23 and 24 pairs of electrodes of second conductive contact film is very little, can not influence the mounting or dismounting of fuse member 30.In addition, because described first conductive contact film 23 and second conductive contact film 24 are measure-alike, so its pressure to electrode is also identical, contact area is also consistent, directly contacts with the fuse-link end cap, has increased contact area, is difficult for outage.
By finding out among Fig. 4, described fuse member 30 is a cylindrical shape cap fuse-link.
By among Fig. 3 as can be known, molten assembly 20 was provided with resistance R and electroluminescence body W in described year, this resistance R and electroluminescence body W series connection back connects two conductive contact films 23 and 24 respectively by lead 27, described electroluminescence body W partly is exposed to and carries molten assembly housing 21 surfaces.Described two conductive contact films 23 and an end of 24 are fixed in by binding post 25 and 26 respectively and carry on the molten assembly 20, and the two ends of the lead 27 of described connection resistance R and electroluminescence body W connect above-mentioned two binding posts 25 and 26 respectively.Binding post 25 and 26 is set fixes two conductive contact films better, improve fail safe, and can make lead 27 and two conductive contact films realize being connected better.
By finding out among Fig. 4, molten assembly 20 also was provided with spacing stop 28 in described year, and these spacing stop 28 1 ends are fixed in and carry on the molten assembly housing 21, and the other end extends to an end of deck 22.When fuse member 30 embedded deck 22, the one end was subjected to the restriction of spacing stop 28, makes its play back and forth, guarantees that so not only two conductive contact films contact evenly with electrode, and, also prevent owing to the inhomogeneous scaling loss that produces of contact.
